JAMES M. DAVIS, OF BAY CITY, MICHIGAN.

VENEER-TAPING- MACHINE.

To all whom it may concern;

Be it known that I, JAMES M. DAVIS, a citizen of the United States,residing at Bay City, in the county of Bay and State of Michigan, haveinvented certain new and useful Improvements in Veneer-Taping Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention is a veneer taping machine and is adapted for pastingpaper strips called tapes, along the end margins of newly made veneer.Such tapes are usually applied to one side of both ends of a sheet ofveneer, to keep the veneer from cracking when being handled.

The invention comprises certain constructions and combinations of parts,as will be more fully set forth in the specification and pointed out inthe claim.

In the drawings, Figure 1 is a front partsectional elevation of themachine; Fig. 2 is an end elevation broken away in part; Fig. 3 is adetail of one corner of the machine as viewed from above; and Fig. 4 isa perspective detail showing a sheet of veneer with the paper tapeapplied thereto.

As is clearly shown in the drawings, the machine consists in a base 1carrying a laterally projecting shelf 2 having openings 8 therein. Inthe base 1 are mounted a plurality of live rolls 4, 5, 6, which may bedriven by any suitable means as for instance a train of gears, asindicated by dotted circles in Fig. 1. The tops of the live rollsproject through the openings 8 and slightly above the top face of theshelf 2.

Above the base 1 is a frame 7 on which are mounted idle rolls, as 8, 9,10, engaging the live rolls 4, 5, 6 respectively. The frame 7 is mountedto slide vertically on rods 11, the lower ends of which are screwed intothe base 1. The rods 11 have adjusting nuts 12 at their upper ends, andbetween the adjusting nuts and the top of the frame 7 are compressionsprings 13 adapted to yieldingly press the rollers 8, 9, 1O downwardlytoward the live rolls 4, 5, 6. The upper idle rolls do not, preferably,come in contact wit-h the live rolls but are normally separatedtherefrom by a space a little less in width than the thickness of theveneer to be operated upon. The spacing of the rolls is effected bymeans of screws 14 screwed Specification of Letters Patent.

into the frame 7 and having their heads arranged to contact with theupper face of the base 1. By means of these screws, the normal clearancebetween the upper and lower rolls may be regulated.

Suitably mounted on the upper frame 7 is a roll of tape 15. A moisteningwheel or glue wheel 16 is provided to contact with the under side of thetape after the tape leaves the roll 15.

In practice a sheet of veneer 17 is fed between the rolls 4 and 8, thetape 18 adhering to the veneer, as indicated in Fig. 4. After the veneerhas passed rolls 4 and 8, the tape is again pressed down and broughtmore firmly into contact with the veneer by passing through rolls 5 and9, and 6 and 10. The tape 18 is fed through the rolls by its contactwith the moving veneer. One sheet of veneer has its side edge buttedagainst the side edge of the next preceding sheet and the sheets arepassed through the rolls in unbroken sequence, being separated from eachother after leaving the machine, the separation being made either by aknife or tearing apart the adj acent sheets.

In practice I prefer to provide means for slightly varying the anglethat the axis of wheel 15 makes with the horizontal, as indicated bydotted lines in F ig. 2, in order to properly guide the tape between therolls 4 and 8, and to accomplish this result I mount roller 15 on abracket 19 which is pivoted at one end 20 to the frame 7, and formedwith a slot 21 to receive a set bolt 22 whereby the bracket 19 may beangularly adjusted.

By the means above described I have pro duced a simple, cheap andefficient machine for rapidly attaching tapes to the ends of sheets ofveneer, and not only accomplish the working more rapidly than hasheretofore been done, but produce a superior quality of work.

Having described my invention, what I claim and desire to secure byLetters Patent, 1s

In a veneer taping machine, the combination of a base, a laterallyprojecting shelf carried by said base and having openings therein, aplurality of live rolls mounted in said base and having their topsprojecting through said openings, a vertically movable frame carrying aplurality of idle rolls, rods carried by said base and slidably receivedin said frame, adjusting nuts on said rods, compression springs on saidrods between said nuts and frame, spacing screws carried by said frameand having their heads in contact with the upper face of said base, atape-carrying wheel, a glue-applying device; an L-shaped bracketcarrying said wheel, the foot of said bracket formed with a verticalslot and pivotally mounted on said frame, a set bolt received in saidslot and adapted to clamp said bracket in various angularly adjustedpositions, for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
